HAL® Lower Limb Type

HAL® Lower Limb Type is a robotic medical device for people who have disabilities in the lower limb and people whose legs are weakening due to disorders of the cerebral and nervous muscular system.

The device fits over a person’s waist and legs and is used in combination with a Body Weight Support System. While working with a trained medical professional (physician, physical therapist), HAL® is programmed to detect faint bio-electric signals on the surface of the skin.

HAL® Lower Limb Model is designed to improve the patient’s ambulatory function outside of the robot, upon completion of the HAL® gait training intervention.

When a patient attempts to move their body, a nerve signal is sent from the brain toward the muscles via the spinal cord and motor neurons. Due to the spinal cord injury, these signals are often too weak to elicit the proper movement of the musculoskeletal system.

These bio-electrical signals are used to drive power units located at the hip and knee joints, allowing the patient to realize the intended movement voluntarily.

Flexible Robot Suit To Fit Various Body Sizes

HAL® Lower Limb Type is full of adjustable elements that allow the device to fit to the patient’s body size and shape (leg lengths, hip widths and foot sizes in wide ranges). With its seamless adjustment mechanism, HAL® can embrace the wearer’s body.

Detachable Controller

With the freely detachable controller of HAL®, the operator can manipulate all the operations, such as start/stop of assistance, alteration of settings and confirmation of motion statuses, closely watching the move of the wearer. Tailor-made assistance for individual wearers makes training with HAL® for Lower Limb Type more effective.
